ABSTRACT:
The present invention provides a method for producing a honeycomb structure which carries a catalyst component containing at least one element selected from the group consisting of alkali metals and alkaline earth metals and purifies exhaust emissions. The method of the invention includes: a starting material mixing step of mixing ceramic particles having a predetermined average particle size, fine particles being composed of the same material as the ceramic particles and having an average particle size smaller than the predetermined average particle size, and an erosion-resistant material or a precursor thereof which inhibits the catalyst component from eroding the ceramic particles more effectively than an oxide of the element contained in the ceramic particles, to prepare a puddle; a molding and firing step of molding the puddle into a molded body and firing the molded body to sinter the molded body and to allow a ceramic particle protection material composed of the erosion-resistant material or the precursor thereof to be present on the surface of the molded body; and a catalyst-carrying step of making the fired molded body to carry the catalyst component.
